UPDATED – Twitter and Bluefin Labs on Tuesday afternoon confirmed by way of their respective blogs that the acquisition that had been trumpeted across social and mainstream media on Monday was indeed happening.

The acquisition price was not disclosed. Twitter said that it will not continue to sell the Bluefin product suite, but will honor current contracts.  With the deal, Twitter not only gets access to Bluefin’s technical acumen, but it also can access the technology and built by SocialGuide analytics and acquired by Nielsen and NM Incite in November.

“This acquisition reflects our commitment to the social TV market, and builds on our exclusive partnership with Nielsen announced in December to develop the Nielsen Twitter TV Rating, the centerpiece of social TV measurement based on Nielsen’s SocialGuide platform.”

“While our products have always included data from multiple social media services, the reality is that Twitter is the platform where the overwhelming majority ­– about 95% – of public real-time engagement with TV happens. So we couldn’t be more excited to join Twitter.”

The acquisition leaves Wiredset’s Trendrr platform and Networked Insights as independent Social TV data providers.

And, it solidifies Twitter’s emerging power in the Social TV market.

Of course, we expect Facebook to counter even though many have written off the social media giant as a relevant player in the Social TV market.
